TURKEY’S President Recep Tayyip Erdogan has claimed victory in the country’s presidential elections after winning a landslide 52.92 percent of the vote, despite fears the contest was rigged.

More than 54 million voters went to the polls on Sunday in the country’s campaign in years, as CHP leader Muharrem Ince galvanised Turkey’s opposition with a series of fiery performances at campaign rallies.

The result is a major boon to the Turkish premier Recep Tayyip Erdogan, who has secured a five-year extension to his 15-year rule and will enjoy sweeping new powers after voters decided to scrap the role of Prime Minister and expand the role of the President in a referendum last year.

But some opposition supporters were claiming the vote had been “rigged” before the final result was even officially announced.

State media reported Mr Erdogan had won 53 percent of the vote with 99 percent of votes counted, with Mr Ince on 31 percent.

I hope nobody will damage democracy by casting a shadow on this election and its results to hide their failure

The landslide victory put Mr Erdogan safely ahead of the 50 percent threshold required to win the contest outright without a second round of voting.

Although Mr Ince has not yet officially conceded, Reuters quoted sources at the CHP who said they would continue their democratic fight “whatever the result”.

In a triumphant victory speech delivered from the headquarters of his party’s headquarters in Turkish capital Ankara in the early hours of Monday morning, Mr Erdogan declared: "The winner of this election is each and every individual among my 81 million citizens."

He added: “I hope nobody will damage democracy by casting a shadow on this election and its results to hide their failure.”

There was widespread scepticism over the fairness of the contest among opposition leaders ahead of the vote.

Concerns were raised over voter intimidation, media bias and electoral fraud, with opposition party CHP arranging thousands of electoral observers to oversee the process.

However, reports almost immediately emerged of ballot-stuffing and forged votes.

A video posted on Twitter appeared to show a ballot box being stuffed with voting slips, while police reportedly arrested three people after finding sacks filled with sealed ballot papers in the back of a car.
